Answer 1

In your url should be like,

 floors.php?id=1&floorno=5

In php file,

You can use,

$id = mysql_real_escape_string($_GET['id']); //output =1. 

$floorno = mysqli_real_escape_string($_GET['floorno']); // output=5 

$query = "SELECT * FROM floors where buildingname='".$id."' and floorno='".$floorno."' ORDER BY floorno 

You may use mysqli_real_escape_string()

mysqli_real_escape_string() calls MySQL's library function mysqli_real_escape_string, which prepends backslashes to the following characters: \\x00, \\n, \\r, \\, ', " and \\x1a

Note: mysql_* deprecated Instead, the MySQLi or PDO_MySQL extension should be used
